The chief Palestinian peace negotiator has thrown his weight behind John Kerry's efforts in the Middle East, Reuters reported on Tuesday.

The US Secretary of State arrives in Oman on Tuesday, the first stop in a week-long regional visit, which will include meetings with Israeli and Palestinian leaders.

Saeb Erekat said Monday that Palestinians have done “everything” to enable President Barack Obama and Secretary of State John Kerry to succeed, and “there is a good opportunity now.”

"We have no conditions to resume negotiations," Erekat told the committee on rights of the Palestinian people, which was created by the U.N. General Assembly in 1975.

"Make no mistake we are exerting every possible effort in order to see that Mr. Kerry succeeds. No one benefits more from the success of Secretary Kerry than Palestinians and no one loses more from his failure than Palestinians," Erekat said.

Kerry is making his fourth visit to the region since taking office, in a bid to re-start peace negotiations between Israel and Palestine.
